Equilibria and kinetics of electron transfer between tris (4,4′-dimethyl-2,2′-bypyridine)-osmium(III)/-osmium(II) and iron(III)/iron(II) in aqueous mixtures of acetone and acetonitrile

Summary

The equilibrium and the kinetics of the title reaction have been investigated in various acetone and acetonitrile aqueous mixtures, by the stopped-flow spectrophotometric technique. The dependence of the reorganization energy on the solvent parameters is discussed.
